Hi, I am a new member in need of help. I am looking for a vacuum diagram for an early carburated XJ12, V12. Some hoses are missing, some hooked up to the wrong place. Thanks.

Post #6 I believe has a file attached which may or may not help... I looked through all my info and the only thing I've got is the carb'd V12 wiring diagram and some S3 V12 stuff. Maybe someone else will have something for you.

And welcome to the forum!

 

Hi Civicalized,

Thank you for your help. Some of my problems are solved by the diagram. I am still looking for info on the small ca. 9/64" or 3.5mm connections on the right hand side of each carburator, close to the mounting studs/nuts and I need the source of vacuum for the advance mechanism. If a diagram is not available pictures would help of a similar version of XJ (Car# 1P5xxxxx and Eng. 7Pxxxxx)
